There is a diversion dam along the channel <br />that helps direct water to the headgate. <br /> <br />Comments: There is a depressed area along the river bank just downstream of the culvert that will <br />allow river flows of greater than 5000 cfs to overtop the bank and flow along the high flow channel. <br />The high flow channel flows back to the river downstream of the Rio Grande Canal headgate. This is <br />an emergency overflow measure to prevent the Rio Grande Canal headgate from being washed out. <br /> <br />Estimated Range of Cost: NIA <br /> <br />F:\Projects\20060507\Documents\Reports\Rio Grande\lnventory Forms\Dyer Ditch.doc <br /> <br />OA No. 2-2006-0507 <br />
